GE Range JBP26W0B1WW, wiring question

Just picked up a used stove and it has a four-wire cord, but my house has an older three position receptacle. Just wanted to run this by the board to make sure my plan is sound. The black and red wires will attach in the same place, the ground will be connected to the center position, and I will run a strap or short wire from the center position to the frame. Correct?
